MATHEW ABT, OF NEW YORK, N. Y.

LUBRICATOR FOR ELEVATOR-GUIDES.

SPECIFICATION forming part of Letters Patent No. 597,251, dated January 11, 1898.

Application filed November 12, 1896- $eria1ll'o. 611,840, (No model.)

To all whom it may concern:

Be it known that I, MATHEW ABT, of New York city, in the county and State of New York, have invented a new and Improved Device for Greasing Elevator-Guides, of which the following is a full, clear, and exact description.

This invention relates to devices for applying a lubricant to the guide-rails for an elevator-car. A

There are at the present time certain lubricants that are not easily spread or applied with a brush while in a normal condition; neither can such lubricants be liquefied by heat to the proper consistency to be applied by a brush. The object of my invention is to provide a device by means of which such thick grease may be evenly spread upon the front and sides of an elevator guide-rail.

My invention consists in a bifurcate receptacle having dischargeports in its inner walls and a plunger for forcing grease through the ports.

It further consists in the construction and novel arrangement of the various parts, as will be hereinafter fully described, and pointed out in the appended claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a section, on the line 1 1 of Fig. 2, of a device embodying my invention; and Fig. 2 is a section on the line 2 2 of Fig. 1;

Referring to the drawings, 1 designates the body portion of a container for grease. This body portion 1 terminates in bifurcate or forwardly-extended leg portions 2, each provided with a port 3 through its inner wall for the discharge of the grease. The end wall 4 of the bodyportion 1 is also provided with a dis-- charge-port 5. Movable in the body portion 1 is a plunger 6, having a stem 7 extended through an opening in the removable cover 8 on the body portion. This stem 7 at its outer end will be provided with a suitable hand- 7 piece 9.

The distance between the opposite inner walls of the portions 2 of the device is substantially equal to the width of an elevator moved.

guide-rail, and preferably the openings 10, I

which provide communication between the body portion and the portions 2,- have an area 4 equal to the discharge-ports 3, and preferably the area of the plunger 6 will be substantially equal to the area of the combined ports 3 and 5, as by such construction the grease may be discharged through the several ports in equal quantities.

In filling the device with grease of course the plunger and cover 8 must be first re- In using the device it may be held in one hand by means of the handle 11, secured to the upper side of the body portion, and then moved up and down upon a guiderail with the bifurcate portions embracing the guide-rail, and during the movements the grease may be gradually forced out by forcing the plunger outward.

I have here shown the device as adapted for manual operation; but it is obvious that it may be rigidly attached to'an elevator, and suitable automatic meanssuch, for instance, as a springmay be employed for forcing the plunger outward to eject the grease.

It will be seen that there is a considerable surface of flat metal around each dischargeport and that these fiat surfaces will serve to evenly spread the ejected grease upon the guide-rail.

Having thus described my invention, I claim as new and desire to secure by Letters Patent--- A device for applying thick grease to an elevator guide-rail, comprising a body portion having an unrestricted discharge-port through its front wall, forwardly-extended side portions provided with unrestricted ports, the openings providing communication between the body and side portions having an area equal to the area of the side ports, and a plunger in the body portion, wider than the front wall and having a front surface area equal to the area of the combined ports, sub stantially as specified.

MATHEW ABT.
